6 Claims. (Cl. 2 14-26) This invention relates generally to the art of handling solids, and particularly to new apparatus for use with an open hearth charging ma chine in cleaning solids from the charging floor in front of an open hearth furnace.

During the operation of an open hearth fur nace various solids are charged into the furnace and some ofk those solids are spilled onto the charging floor in frontl of the furnace. Heretofore such solids have been cleared away by hand shoveling which necessitated the expenditure of considerable labor. The present invention provides apparatus which can be operated by the charging machine to clear away substantially all such solids without the expenditure of any substantial amount of hand labor.

Altho the herein illustrated and described em bodiment of the present invention is especially suited to use with a charging machine, it will be understood that other devices embodying the invention may be used with other types of actuating apparatus which are capable of shifting such a device to scraping, carrying, or dumping positions and of propelling it during the loading operation. For example, the attaching means at one end of the box herein illustrated may be altered to fit a suitable arm on an automobile, tractor or other wheeled vehicle for use in scraping up solids and transporting them to a place where they are to be dumped.

The present invention will be better understood by those skilled in the art from the following description and the drawings which accompany this specification and in which,

Figure 1 is a fragmentary perspective View showing a box constituting one embodiment of the invention and adapted for use with an open hearth charging machine;

Figure 2 is a top plan view of the box of Fig. 1;

Figure 3 is a cross-sectional view taken on line 3-3 of Fig. 2;

Figure 4 is an elevational View of the righthand end of the box of Fig. .2;

Figure 5 is a lefthand elevational view of the box of Fig. 2; and,

Figure 6 is a side elevational view of the scraper side of the box of Fig. 2.

Figure 1 shows the front of an open hearth furnace I, a charging Iioor 2 having rails 3 for charging box cars and one rail 4 of a charging machine track. The peel 5 of a charging machine (not shown) is connected at its free end to a box 6 for scraping up solids on floor 2 and transporting them to a place of disposal, for example, dirt box 1.

VThe box 6 of Fig. 1 is shown in more detail in Figs-2 to 6 inclusive. This box is open-topped and has a bottom Ill, a low end II, a high end I2, a low side I3, and a high side I4. The high end I2 is provided with a wall I5 spaced apart therefrom and slottedas at I-B to receive the free end of peel 5 and'isalso providedwith holes I'I to receive pins at the end of the peel. When the free end oi the peel 5 is inserted between the-end wall I2 and spaced wall I5 and the pins are inserted in holes II, the box may be lifted, rotated and moved endwise by the peel and' also moved sidewise when the charging machine runs along its rails.

' Strengthening ribs 20 extend along the outer surface of bottom I and side I4 substantially parallel to ends II and I2 of the box. Each of these ribs merges into an offset ange 2l which extends along the upper edge of side wall Ill. A corresponding oiset flange 2'2 extends along the upper edge of the low end II of the box and another similar oiset flange 22.extends along the upper edge of the high end I2 of the box. The ribs and the adjacent ends of iianges 2I define spaces 23 therebetween for a purpose presently 25 to appear.

It will be noted that the upper edge of side I4 of the box is inclined at an acute angle to the bottom Ill of the box and that the low and high ends of the box have integral wings 25 and 26, respectively, which extend part way across the ends. A scraper blade 2I is disposed on the inclined upper edge oi side I4 of the box and has ends 28 which extend along the ends of the box. Blade 2l has substantially parallel longitudinal edges, one of which bears against the upper edge of side I4 of the box while the side surface of the blade bears against the inner surface of offset flanges 2I. Similarly, theends 28 of the blade rest on the upper edges of ends I I and I2 and bear against anges 22. This blade with its ends constitutes extensions of side I4 and ends II and I2 of the box. Blade 2'I has exterior, integral, yribs 29 which extend downwardly below its lower edge, lie in the spaces 23 parallel and adjacentto ribs 20, and may be detachably connected to those ribs, as by bolts and nuts 39. Additionally, bolts g; detachably secure the blade to flanges ZI and When the box of Figs. 2 to 6 inclusive is mounted on the peel 5 of a charging machine, the free edge of blade 2l may be brought into contact with the charging floor 2 and the box may be propelledY along the floor with the result that solids on the oor will be scoopedy into the box. The box may be rotated into an upright position 3 and the solids therein may either be charged into the furnace in the ordinary charging box manner or may be dumped into box l.

Having thus described my'invention so that others skilled in the art may be able to understand and practice the same, I state that what I desire to secure by'Letters Patent is deiined in what is claimed.

What is claimed is:

l. A iioor scraping device comprising an open topped box having a bottom, sides and ends, ribs parallel to said ends and projecting outwardly from the bottom and one side of the box, ablade attached to said ribs and bearing 0n the top edges of said side and the ends of said box,fand.me'a`ns at one end of the box for connecting it to the peel of a charging machine.

2. A oor scraping device comprising an open topped box having sides and ends, ribs parallel to said ends and projecting outwardly from one side of the box, oiset fiangesextending from each of said ribs along the upperredge of said rib-bearing side of the box, a blade bearing against the upper edge of said side and against said ianges, ribs extending from said blade along the ribs of said side and attached thereto, and means at one end 4oi the box for connecting it to the peel of a charging machine. Y

3. A door scraping device comprising an open topped box having a bottom, sides and ends, a blade attached to the box and constituting an extension of the ends and one side ofthe box, said blade having a free edge disposed at an acute angle to said bottom of, the box, and'means at one end of the box for connecting it to the peel of a charging machine. Y Y

4. A floor scraping device comprising an open topped box having a bottom, sides and ends, one of said sides having an upper edge inclined at an ,acute angle to said bottom of the box, a blade attached to the box and constituting an extension of the ends and said side of the box, said blade having a free edge substantially parallel to the upper edge of said side of the box, and means at one end of the box for connecting it to the peel of a charging machine.

5. A iioor scraping device comprising an open topped box having a bottom, sides and ends, one cf said sides having an upper edge inclined at an acute angle to said bottom of the box, ribs projecting outwardly from said side parallel to said ends of the box, offset anges along the upper edge of said side, a blade having parallel longitudinal edges, and ribs extending beyond one of its edges to lie beside the ribs of said side of the box when the blade bears against the upper edge of said side and said oiset anges, means connecting said ribs of the blade to the ribs of the box side, and means at one end of the box for connecting it to the peel of a charging machine. 6. A floor scraping device comprising an open topped box having a bottom, sides and ends, eX- terior reinforcing ribs integral with said bottom and one side and parallel to said ends, a scraper blade detachably connected to the ribs-of said side of the box, said blade constituting an extension of said side and having a free edge inclined at Van Vacute angle to the bottom of the box, and means integral with one of said ends for connecting said box to the peel of an open hearth charging machine. v
